Application flledlllar'oh 21, 1918. serial No. 755,994.

To all whom it may concern Be it known that I, WnZL'IAM Banno'n, a citizen of the United States, residing at Bellingham, in the county of Lhe qui Parle and State of Minnesota, have invented certain new and useful Im rovements in Looks for Engine-Hoods; an I do hereby declare the followin to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which,

it appertains to make 'and use the same.

This invention comprehends improvements in locks for engine hoods and relates more particularly to means whereby the hoods covering the engines of motor vehicles may be conveniently locked against the frame.

Another and more specific object of the invention resides in the provision of locking means of this nature which may be operated from the drivers seat and which when in operative position, will efi'ebtually prevent the hood sections being raised.

Another and more specific object of the invention resides in the provision of lucking means of this nature, which shall be semi-automatic in operation, simple, durable, and capable of easy application to the common types of motor vehicles now in use.

lVith these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction,- combination, and arrangement of parts, as will be hereinafter described and claimed.

For a complete understanding of the invention reference is to be had to the following description and accompanying drawing, in which,

Figure 1 is a side elevation partlym section and partly broken away, showing my improved locking means in operativeposition upon a motor vehicle, Fig. 2 1s asunilar view, showing the locking means in its inoperative position, Fig. 3 is a view looking against the right hand end of Fig. 1, Fig. 4 is a vertical sectional vlew through the hood and a portion of the locking means, and, Fig. .5 is a top plan view of the locking means per 86. v

Referring in detail to the drawings by numerals, 6 designates the frame of a motor vehicle, 7 supporting bars attached thereto, 8 the radiator, and 9 and 10 the hinged sections which form the hood. These parts as well as the dash-board 11 and foot-board 12,

may be 'of any desired construction and are only shown to illustrate the application of my lockin' mechanism.

The Ice in" mechanism includes a foot lever 13 which is pivotally mounted intermediate its ends upon a supporting rod 14 which extends under the foot-board 12. The lever works through a slot 15 formed in the foot-board and has pivotally connected adjacent its upper extremity a forwardly extending lock bar 16, said bar being bifurcated at its inner end and secured to the lever by means of a fastener 17. The lock bar slides through an opening 18 formed in the dash-board and is formed adjacent its outer end with an opening 19 through which a latch 20 is adapted to project so as to hold the bar against movement. This latch is spring-pressed and forms part of a lock 21 which is positioned within the hood and attached to the dash-board 11. The latch may be retracted by means of a removable key 22 which may be inserted into the loci; through the dash-board.- A and 23 is pivotally supported upon the oot-board and by engaging in a notch 24'serves to hold the upper end of the foot lever in its forward position.

A transverse rod 25 extends throu h and is rigidly fixed within an opening ormed adjacent the lower terminal of the foot lever and is provided for the purpose of reciprocatin the locking pins 26 and 27. Locking ms 26 are held on the rod 25 by means of t e nuts 28. These pins 26 and 27 are supported under the bars 7 by means of the guide brackets 29. The pins 26 are straight whereas the pins 27 are formed with off-set portions 36 which are connected at their inner ends to the first mentioned pins at a distance from their outer ends, as clearly shown in Fig. 1.

A contractile spiral spring 31 tends to hold the locking ins in their forward position, at which time the project through eye-bolts 32 depending fi 'om the laterally projecting flanges 33 of the hood sections 9 and 10. The flanges rest upon the supporting bars 7, which latter are slotted, as indicated at 34, to permit the hood sections bein swung about the pintle 35.

ilaving described my locking mechanism, it now remains to explain the operation thereof: \Vhen the arts are arranged as shown in Fig. 1, the ocking pins 26 and 27 extend through the eye-bolts 32 and make it, impossible to raise the hood sections. The spring latch 20 is extended through the opening 19 in the lock bar so that it is impossible to actuate the foot lever so as to retract the locking pins. Before this last operation can be accomplished the spring latch 20 must be retracted and this can only be done by insortinga proper key within the lock 21. llaving withdrawn the spring latch from the aperture 19, the upper terminal of the foot lever may be forced for wardly and held in such position by means of the pawl 23. The forward movement of the upper terminal of the foot lever swings the transverse bar 25 rearvvardly and the locking pins are withdrawn from the eyebolts. i

From the foregoing description taken in connection With-the accompanying drawing,

it will be apparent that l have provided an extremely simple and efficient locking inechtll'llSll'llYlllCll will effectually prevent the hood being opened by unauthorized persons.

it is to be understood that while it have shown and described the preferred embodiment of my invention, 1 do not wish to be limited to this exact construction,con1bina tion, and arrangement of parts, but; may make such changes as will fall within the spirit and scope of the invention.

Having thus described my invention, what ll claim is 2- l. 'llheconibination with a motor vehicle,

nioaaae including an engine hood, of eye-bolts depending from said hood through slots formed in the frame of the vehicle, sliding fasteners positioned under said frame and adapted to "extend through the eye-bolts, a foot lever pivoted intermediate its ends to the foot-board of the vehicle, means connecting said lever with the sliding fasteners, spring means for holding said fasteners normally in their operative positions, and means for locking the foot lever against movement.

2. The combination with a motor vehicle, includingan engine hood, of eye-bolts de- 'iending from said hood through slots formed in the frame of-the vehicle, sliding fasteners positioned under said frame and adapted to extend through the eye-bolts, a foot lever pivoted intermediate its ends to the foot-board of the vehicle, means connectingvsaid lever with the sliding fasteners, spring means for holding said fasteners normally in. their operative position, a lock bar connected at one end to the foot lever and projecting into said hood, and lie actuated means for engagement With sai loclr bar whereby the same is held against movement.

In testimony whereof ll affix my signature in presenc/e of two witnesses.
